Answer: 65.25 u²
Explanation:
I'm going to flip the triangle so c is at the bottom. i draw a height from <C down to c so that I create a right triangle and I will use trig to find h
they gave me b (hypotenuse) and <A and i want that new h we drew which is opposite <A
sin A = b/h
sin 65 = 18/h cross multipy to bring h up
h=18/sin65
h=16.31
Area= 1/2 b h b=base=c=8
=1/2 (8)(16.31)
=65.25 u²
